IEC 61675-3:1998

Radionuclide imaging devices - Characteristics and test conditions - Part 3: Gamma camera based wholebody imaging systems

IEC 61675-3:1998 specifies test methods for describing the characteristics of gamma camera based wholebody imaging systems. As these systems are based on Anger type gamma cameras this part of IEC 61675 should be read in conjunction with IEC 60789. The test methods specified have been selected to reflect as much as possible the clinical use of gamma camera based wholebody imaging systems. It is intended that the test methods be carried out by manufacturers, thereby enabling them to describe the characteristics of gamma camera based wholebody imaging systems.

Dispositifs d'imagerie par radionucléides - Caractéristiques et conditions d'essai - Partie 3: Systèmes d'imagerie du corps entier à gamma-caméra

La CEI 61675-3:1998 a pour objet de spécifier les méthodes d'essai relatives à la description des caractéristiques des systèmes d'imagerie du corps entier à gamma caméra. Dans la mesure où ces systèmes sont basés sur des gamma caméras de type Anger, il convient de lire la présente partie de la CEI 61675 conjointement avec la CEI 60789. Les méthodes d'essai spécifiées ont été sélectionnées afin de refléter autant que possible l'utilisation clinique des systèmes d'imagerie du corps entier à gamma caméra. L'objectif est de faire appliquer ces méthodes d'essai par les fabricants, leur donnant ainsi les moyens de décrire les caractéristiques des systèmes d'imagerie du corps entier à gamma caméra.

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, the IEC publishes International Standards. Their preparation is
entrusted to technical committees; any IEC National Committee interested in the subject dealt with may
participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization
for Standardization (ISO) in accordance with conditions determined by agreement between the two
organizations.
2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61675-3 has been prepared by subcommittee 62C: Equipment for
radiotherapy, nuclear medicine and radiation dosimetry, of IEC technical committee 62:
Electrical equipment in medical practice.
The text of this standard is based on the following documents:
FDIS Report on voting
62C/211/FDIS 62C/221/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
In this standard the following print types are used:
– requirements, compliance with which can be tested, and definitions: in roman type;
– explanation, advice, introductions, general statements, exceptions and reference: in smaller roman type;
– test specifications: in italic type;
– TERMS USED THROUGHOUT THIS STANDARD WHICH HAVE BEEN DEFINED IN CLAUSE 2 OF THIS
STANDARD OR LISTED IN ANNEX A; SMALL CAPITALS.
The requirements are followed by specifications for the relevant tests.
Annex A is for information only.
A bilingual version of this standard may be issued at a later date.

Part 3: Gamma camera based wholebody imaging systems
1 General
1.1 Scope and object
The object of this part of IEC 61675 is to specify test methods for describing the characteristics
GAMMA CAMERA BASED WHOLEBODY IMAGING SYSTEMS
of   . As these systems are based on Anger
type GAMMA CAMERAS this part of IEC 61675 should be read in conjuction with IEC 60789.
Two additional tests, scanning speed constancy, and system SPATIAL RESOLUTION without
scatter, shall be performed. Measurement of system uniformity for wholebody imaging systems
is possible but difficult to perform because of the requirement for large and uniform sources.
Most of the potential problems that could affect uniformity will also affect the system resolution,
and therefore such a uniformity test is not included in this standard.
The test methods specified in this part of IEC 61675 have been selected to reflect as much as
possible the clinical use of GAMMA CAMERA BASED WHOLEBODY IMAGING SYSTEMS. It is intended
that the test methods be carried out by manufacturers, thereby enabling them to describe the
GAMMA CAMERA BASED WHOLEBODY IMAGING SYSTEMS
characteristics of   .
1.2 Normative references
The following normative documents contain provisions which, through reference in this text,
constitute provisions of this part of IEC 61675. At the time of publication, the editions indicated
were valid. All normative documents are subject to revision, and parties to agreements based
on this part of IEC 61675 are encouraged to investigate the possibility of applying the most
recent editions of the normative documents

3 Test methods
All measurements shall be performed with PULSE AMPLITUDE ANALYSER WINDOW as specified in
table 1 of IEC 60789. Additional measurements with other settings as specified by the
manufacturer can be performed.
Before the measurements are performed, the system shall be adjusted by the procedure
normally used by the manufacturer for an installed unit and shall not be adjusted specially for
the measurement of specific parameters.
Measurements of performance parameters in the planar mode of operation are a prerequisite.
A complete set of performance parameters shall be measured as specified in IEC 60789.
Unless otherwise specified, measurements shall be carried out at COUNT RATES not exceeding
20 000 counts per second.
3.1 Scanning constancy
Scanning constancy shall be measured using a POINT SOURCE attached to the DETECTOR HEAD
and expressed as COUNT RATE deviation along the full scanning length.
3.1.1 RADIONUCLIDE
99m 57
The RADIONUCLIDE to be employed for this measurement shall be Tc or Co.
3.1.2 Source
The source shall be a POINT SOURCE attached to the COLLIMATOR at the centre of the field of
view. The ACTIVITY of the source shall be adjusted to yield a COUNT RATE between 10 000 and
20 000 counts per second, through a 20 % analyzer window, in the DETECTOR FIELD OF VIEW.
3.1.3 Data acquisition and analysis
The scan speed and the acquisition matrix shall be in the range recommended for clinical use.
Two scans shall be per
